Salmonella serovar surveillance in Poland’s food chain (2016–2020)
A recent study published in Pathogens provides a comprehensive update on Salmonella serovar distribution across Poland’s food chain between 2016 and 2020. A total of 7104 isolates were serotyped, revealing 175 distinct serovars.
Dominant Serovars: S. Enteritidis (40.9%), S. Infantis (16.4%), and S. Typhimurium (5.1%) together accounted for over 60% of all isolates across the food chain.
Animal-Specific Patterns: Chickens: High prevalence of S. Enteritidis (57.2%) and S. Infantis (16.9%). Ducks: S. Enteritidis most frequent, followed by S. Senftenberg and S. Anatum. Geese: Predominantly S. Typhimurium (36.3%) and S. Enteritidis (29.7%). Turkeys: Most serotypically diverse; S. Kentucky was most common (23.4%). Pigs: Monophasic S. Typhimurium (36.8%) and S. Derby (25.4%) predominated. Food Chain Observations: In poultry meat and processing facilities, S. Enteritidis and S. Infantis were the leading serovars. Temporal Trends: From 2016 to 2020, S. Enteritidis and S. Infantis showed increasing prevalence, whereas S. Mbandaka declined. Monophasic S. Typhimurium became more prominent, particularly in swine.
Poland is one of the leading poultry producers in Europe. 1st in the EU for poultry meat production, with the highest volume of broiler meat, primarily chicken, destined for both domestic consumption and export. Among the top producers of table eggs, supplying both national and European markets.
